SWITCH AND FUSE SUPPORT AND covnn.

" asmsa.

it 1 switch and fuse supports and covers and it has for its object toprovide means wherehv when l'lK cover is in place upon the support. thev indiridtml polarities, that is the mountings indconnectionsconstituting thesame. will 15 be separated from each other hysuitable insulatine walls, but when the cover is re- ,movcd the saidseparatinglwalls will also be removed so that the mountings and connec-1ons upon the base of the support shall be zgireadily accessible. 7

8 designates cut-outs or fuses which are, supported in the springclipsit). the said clips being arranged in pairs as illustrated v inFin. 2.

The groups of binding posts 7, clips 9, and

vcut outs or fuses 8. are respectively designated as polarities, thesaid term being one of relationship indicating that the (11ft'ereutgroups are of dltle'rent polarlties,-

plus or minus.v 1

Extendingpar'tiallv around the outer edge portion oi the base 1 .of thesupport is'a groove 10 into which a head or elongated projection 11 fromthe cover 12 projects or fits. The said base 1 is also provided withvrecesses 15 into which projections ltion the cover extend when the.cover is in place.

It should be noted here that the cover is provided with grooves and 21which are ctnnpleuiental to the. grooves l and 5 in the basefl ,aii tlalso that the said cover is pro- \lt lfl v dirll a projection 22 whichis complenujnta .to the projection 2 .on the base .1.

Thecover is provided with recesses 25 separated by wall portions 26asindieated in Fig-s1 and 3 of the drawings. -When the cover is in placeit will be observed that. the individual polarities are located in thesaid recesses 25 in the cover and that the, wall portiotisQtt of thecover separate and insu: late the said individual polarities from eachother. By reason oi the fact that the partsor ose oi. heim repaired orfor anv other purpose. The cover is secured in position by means ofscrews 30 situated preferably" at three of the corners of the device anda fourth screwprbolt 31 situated preferably at; the remaining cornerofthe device. The latter screw bolt is provided with awing nutZiQWhIlClIiS prevented, by means of a seal 33,.tro1u being turned forthe purpose of ren'ioving it and thereby permitting the removal of thescrew bolt 31.

socket into the regionof the base or sup; port 1. When fitted up thewires preferably For the purpose of protecting the screws and otherportions of the mountings on the base 1 which extend through the saidbase,

I have provided a plate on the lower side of the said base. The screwshave screwthreaded engagement with bosses 36 which may formed integrallywith or separately tron: ie said plate and then secured thereto bysoldering or otherwise. The said screws 30 may be the only means forsecuring said plate in position, although I prefer to employ additionalscrews 40 for that purpose.

These screws 40 engage bosses 41 on the provided the perforationsthrough the said cover. By means of these grooves the air is permittedto circulate with substantial freedom about the mountings ot' the saidbase or support and thus the liability of the parts becoming overheatedis reduced to a minimum. Also by reason of the tact that the plate 35 isfree from openings or pertorations the air which may become heatedHaving thus described my invention, I claim 1. In a switch and fusesupport,'the combinationof a base member, electrical connections securedthereon, and a cover secured to said base member, the said cover havingcavities in its inner side into which the said connections extend whenthe said cover is in place and also having separating walls between thesaid cavities.

2. In a switch and fuse support, the combination of a base member,electrical connections secured thereon, and a cover secured to said basemember, the latter having grooves in its lower side, and both the basemember and the covering member having perforations extendingtherethrough and being in communication with the said grooves for thepurpose of permitting circulation of air around the said connections.

3. In a switch and fuse support, the combination of a base member,electrical connections secured thereon, a protecting plate secured tothe lower or bottom side of the said base member, a cover adapted to hesocured to the said base member, the latter member having grooves in itslower side and the said base mci'nbcr and cover having perforationsextending therethrough which perforations are in communication with thesaid grooves in the base member for the pur- 1 pose of permitting"circulation of air around the said electrical connections and between byreason of the heating of the electrical connections or which may alsobecome. heated by the blowing out of a. fuse or fuses and which islocated between the plate 15 and the base 1 escapes through theperforations 46 in the base 1 and the perforations 50 in the cover ofthe support. It will be understood that the air may circulate betweenthe plate 35 and the base 1.

The base may be secured in any suitable manner to a supporting means butI prefer to employ screws. or bolts (not shown) which extend throughopenings 51. in the base and connect with the supporting means.

In order that the space between the supporting means and the plate 35may have communication with the outside air. I provide notches 52 in theedges of the bottom otthe base 1.

The base and cover parts ol the support consist of a suitable insulatingmaterial, such as porcelain.

the said plate and the said base.

i. In a switch and fuse support, the combination of a base member,electrical connections secured thereon and projecting above its top orupper side, a cover adapted to be secured to the said base men'iber,the. said cover having cavities in its inner side into which the saidconnections extend when the said cover is in place, and the said coveralso having walls between the said cavities which separate the saidconnections when the cover is in place, and the said base and coverhaving perforations extending therethrough which comnnu'iicatc with thesaid *cavities and permit irculation ol' air around the saidconnections.

In testimony that I claim the tort-going as my invention, I havehereunto signed my name this 1st day of July, A. D. 1910.
